Solution
1. Preparation
  • Gather tools: multimeter, socket set, screwdrivers, and wire connectors.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
2. Check and Replace the Fuse
  • Locate the fuse box (usually in the glove compartment or under the dashboard).
  • Remove the power window fuse using a fuse puller.
  • Inspect the fuse for any signs of damage or breakage.
  • If damaged, replace it with a fuse of the same amperage (refer to the vehicle manual for specifications).
3. Test the Power Window Switch
  • Remove the door panel carefully using a screwdriver and trim removal tool.
  • Disconnect the power window switch connector.
  • Use a multimeter to measure continuity by pressing the switch.
  • If no continuity is detected, replace the switch with a new one.
4. Inspect and Repair Wiring
  • Examine the wiring harness for frays, breaks, or corrosion.
  • Repair any damaged wiring with soldering or appropriate wire connectors.
  • Reconnect the wiring harness.
5. Test the Window Motor
  • Disconnect the window motor from the window regulator.
  • Using jumper wires, connect the motor directly to a 12V battery to test its operation.
  • If the motor does not operate, replace it with a new window motor.
6. Reassemble the Door Panel
  • Reattach the door panel by aligning it with clips and screws.
  • Ensure all connections are secure and that no tools are left inside the door.
